Abstract

Background Turner syndrome ( TS ) is the most common sex chromosome abnormality in women and is associated with increased morbidity and mortality. We describe long‐term outcomes in a large cohort of patients with TS . Methods and Results Retrospective review of patients with TS followed at Mayo Clinic Rochester from 1950 to 2017 was performed. Clinical, imaging, surgical, and genetic data were analyzed. Survival analysis was performed with the Kaplan–Meier method using age‐ and sex‐matched Olmsted County residents as the reference group. The study cohort comprised 317 patients with TS . Average age at diagnosis was 9 (range, 2–12) years, genetic testing was performed in 202 (64%), and pure monosomy X was present in 75 (37%). Congenital heart disease occurred in 131 (41%), with the most frequent lesions being bicuspid aortic valve (n=102, 32%) and coarctation of the aorta (n=43, 14%). Ascending aortic dilation was common, with mean aortic root size index 2 cm/m 2 , and aortic dissection occurred in 6 (2%) patients. The average follow‐up was 11 (range, 2–26) years, yielding 3898 patient‐years, and during this period 46 (14%) patients died; mean age at the time of death was 53±17 years. Patients with TS had reduced survival compared with the control group (82% versus 94% at 30 years; P <0.001), and the leading causes of death were cardiovascular disease, liver disease, and malignancy. Conclusions Patients with TS have reduced survival compared with age‐matched controls, and cardiovascular disease is the major cause of death. Further studies are required to determine if targeted cardiovascular risk factor modification will result in improved survival in this population.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
